| 摘 要： | 为了了解浙江省涂膜柑橘贮藏期烂果风险的时空分布规律及其近60年的变化特征,利用1961—2016年常规站日气象观测资料,以涂膜柑橘贮藏腐烂阈值及各时段发生的频率为区划指标,采用距离权重反比法(IDW,Inverse Distance Weighted),开展了柑橘贮藏期烂果时间阈值风险区划,并分析了它的年代际变化。结果表明:2006年以后,浙江涂膜柑橘贮藏期烂果出现的时间越来越早,且从西南地区到东北地区柑橘贮藏期烂果出现时间逐渐推迟。最晚时间西南部地区在3月上旬,中西部地区和沿海南部地区在3月中旬,其他地区在3月下旬。21世纪10年代前6年与20世纪60年代相比较,丽水涂膜柑橘贮藏最早烂果时间从3月第1候提前到2月第4候,而最晚时间从4月第4候提前到第1候。区划结果将为橘农合理安排柑橘贮存、及时进行贩销提供参考和科学依据,从而减少对柑橘贮藏品质的影响。

| Abstract: | In order to understand the spatial and temporal distribution of the risk of rot diseases of coated citrus during storage and its change characteristics in recent 60 years in Zhejiang province, the time threshold risk zoning of perishable citrus was carried out and its inter decadal variation was analyzed by using the daily observed data of meteorological station from 1961 to 2016, taking the threshold and the frequency of rot diseases of citrus in each period as the index and using the inverse distance weight method (IDW). The results showed that the time of rot diseases of coated citrus in storage in Zhejiang province appeared earlier and earlier after 2006 and delayed successively from southwest to northeast. The latest storage time of coated citrus was in the first ten days of March in the southwest, in the middle of March in Midwest and southern coastal areas, and in the last ten days of March in other areas. Compared with the 1960s, the earliest time of rotten fruit storage of Lishui coated citrus in the 21st century was advanced from March 5th to February 20th, and the latest was advanced from April 20th to April 5th.The results of regionalization could provide reference and scientific basis for orange growers to arrange the storage of citrus reasonably and sell citrus in time, so as to reduce the risk of impact on the quality of citrus storage. |
